MACHINE FOR DYEING BOBBINS AND THE LIKE.

, Specification of Letters Patent; Application filed February 28- 1906- 'Serial No. 302-391 Patented Feb. 4, 1908.

To all whom it may concern:

Be it known that I, CoNnAnWANsLnBEN, a subject of the King of Prussia, residm at Crefeld, 'in the Kingdom of Prussia and erman Empire, have invented new and useful Improvements in Machines for Dyeing Bobbins and the Like, of which the following is a specification;

My invention relates to improvements 1 n machines for dyeing cops, bobbins and similar goods, and the object of my invention is to provide suitable means for first imbibing the said cops, bobbins or goods with the liquidv dye, and. for immediately afterwards removing the surplus ofliquidby way of suction, the current of atmospheric air drawn through the co s or bobbins servin at the same time, if (Tesired, to develop tie color applied thereto.

In dyeing cops, bobbins and other goods with indigo and similar colors it is of great importance, not only to remove the surplus -of dye-liquor immediately after removing the goods from the bath, but also to force a current of atmospheric air through the goods, which in a known manner acts to develop the color. If, after-leaving the dyebath, the cops or bobbins or similar goods are left to remain in their wet condition for any considerable length of time, no uniform shade is obtained, as the color becomes spotted. Numerous devices therefore, have already been tried to remove the superfluous liquor immediately after the immersion of the goods in the dye-bath.

The improved machine constructed according to my invention, performs the work in a continuous operation and requires but very little labor on the art of the operator.

A traveling apron or be t carries the cops or bobbins into the dye-bath at one end of the machine and delivers them at the op osite end, said belt or a ron being provide with suitable holes and hollow pins or nipples secured within said holes to receive the cops or bobbins, which are placed on said ni ples by hand at the entrance end of the mac me and are taken ofi at the delivery end, as the 0011-. tinuously moving apron slowly emerges from the dye bath. The slow and uniform motion of the apron facilitates the placing and removing of the cops or bobbins and also prevents the said cops or bobbins from falling off the said apron, while it passes into the bath and emerges therefrom .on an inclined plane, The dye-bath becomes but very and belowthe said slotted bottom is arranged a channel or air chamber commumeating with the cistern through the said slots. A suction pipe or pipes connected to an air pump terminate in the said channel or chamer. The apron carrying the cops or bobbins, while moving through the cistern, is dragged along the bottom of the same, thereby preventing the dye-liquid from flowing through the slots of the bottom into the chamber below it. If the apron were solid, no communication would exist between the cistern and the chamber below its bottom, in spite of the slots therein. The apron, therefore, is perforated and in said perforations are secured hollow pins or ni ples on which the bobbins are mounted. When suctional force is a plied to the chamber below the cistern, the liquid dye will be drawn int-o the cops or bobbins, thereby imbibing the yarn of the cops or bobbins from the outside to the inmost core. The liquor passes through the yarn and then through the perforations inthe apron into the chamber below the cistern, from where it is removed by the suction, which delivers the liquor to any suitable reservoir from which it may be returned into the cistern.

The belt or apron, on leaving the cistern is made to pass along the slotted or perforated top or cover of an air-chamber, which is connected to an exhaust )ump. The holes or perforations in the said top or cover will be closed by the apron, except at those arts, where the said apron is perforated. I t will be seen then that, by means of the suctional force acting from below the traveling apron, air will be drawn from the outside through the cops or bobbins, the perforated apron and the perforated top of the air chamber, and along with the air theliquid dye still contained in the yarn of the cops or bobbinswill be removed from the yarn and passes into the suction chamber from where it will be carried off through the suction pi e or pipes connected therewith and delivere into a suitable reservoir from which it may also be returned to the cistern.

To better illustrate my invention, reference is made to the accompanying drawing inwhich t Figure 1 is a lon 'tudinal section of the new apparatus and ig. 2 a transverse section.

The tank or cistern a, which is supported on a suitable frame, contains the dye-bath. The bottom of said tank or cistern is preferably raised through the greater part. of the length of the cistern and is provided with the slots 8, extending in the direction of the. length of the tank, whereby the, latter communicates with a channel or chamber h, arranged below the raised bottom. One or more suction pipes open into said channel connecting it wlth an exhaust pump not shown in the drawing.

An endless belt ora ron b pa'sslng over a pair of drums arrange at both ends of the tank a is uided by idlers so that it is drawn through the tank in close contact with the slotted bottom thereof, so that the slots 8 in said bottom are tightly covered by the apron passing over them.

,At the delivery end of the tank a, where the beltor-apron 1) passes out of the same to a higher plane,.an alr-chamber-c, is provided within the frame of themachine, said airchamber being arranged in the line of motion of the traveling belt or apron b. The top or cove-rd of said chamber c is slotted'or perforated in the direction of its length, and

' the belt or a ron b, on passing over said top or cover, tig tly' closes the slots or perforations against the outside atmosphere. An'

" exhaust pipe coming from an exhaust pump terminates into saidair chamber 0, 'to produce .a vacuum the same.- The traveling belt or apron b is provided,

' in the direction of its length, WltltOIlG or the apron descends into the d' e-bath in said tank. The cops orbobbins t us are carried 'slowl with uniform movement through the liqui dye without causing any material a 'tation therein, which might be objectiona le. During this time, the cops or bobbins, as will be seen from Fi 1, become totally immersed into the'dye-iath. At the right hand end of the tank in Fig. 1, the belt or aproncarrying the cops or bobbins is raised out of the bath and passes over the perforated or slotted top or cover (1 of the airchamber a.

Motion is imparted to the driving drum in a well-lmown manner.

If desired, chains may be attached. to the sides of the belt or apron b, to be engaged by corresponding sprocket-Wheels, whereby a true guiding of the belt or apron is obtained. it will be easily understood that, as the belt or apron b, with the cops or bobbins carried thereby, slowly passes .over the slotted bottom of the tank a, the liquid in said tank will be prevented from flowing through the slots s, into the channel or chamber h, as the slots 8 are tightly covered by the belt. When, how ever, through the suction-pipe, terminating into the channel h, a vacuum is created within the same, the liquid dye is forced throu h the yarn of the cops or bobbins place onto the belt, and; thus passes through the sockets or nipples n and t e holes in the belt or apron and the slot 8 in the bottom of the tank a. into the channel h, from which the liquid is drawn ofi and delivered to a suitably located tank or reservoir not shown, from which it can be returned to the tank a.

- The cops or bobbins leave the dye-bath thorou hly soaked with the liquiddye. The

- latter, owever, must be drawn out again, as

soon as the cops or bobbinshave left the bath. To this purpose, the apron is guided over the suction chamber .0. By producing a vacuum in said chamber, air is drawn through the cops or bobbins, and while thus'f air is orced through the yarn, also the liquid 'still contained in the yarn is drawn into the chamber, 0, from Where it is drawn off by the suction-pipe terminating in said chamber. The forcing of air through the Wet bobbins influences the color to develop the same; the right hand end of the machine, in Fig. 1, the cops or bobbins are taken off beforethe belt descends to pass under the tank a back to the opposite side thereof. at I claim is In an apparatus for dyeing cops, bobbins and similar goods, the combination with a tank containing the liquid dye, and having a channel provided in its bottom, the said bottom having openings therein, a suctionpipe terminatin in said channel, an air chamber at the elivery end of the said tank arranged in line therewith and having a perforated top-plate, an exhaust-pipe terminating in said air-chamber, a perforated apron adapted to receive the cops or bobbins, means to move said apron in contact with the perforated bottom of said tank and over the perforated top of the said air-chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 1
